Accidentally pulled out stem from antique pocket watch.


Recommended Posts

Hello, I'm Steve, proud owner of my grandfather's pocket watch, a wedding present to him from my grandmother a hundred years ago.

I accidentally pulled out stem from an antique pocket watch.  Replaced it, but stem is loose and moves the watch hands, but does not wind the spring. Can it be repaired or must it be replaced?  No one supposedly knowledgeable has been able to identify the manufacturer.  It was purchased in Germany in 1921. Thanks for any help.

ill a really be nice to have a picture? this is because pocket watches and how the stem works can have a lot of variations that really helps to give us a picture.

Then where is the moderator when we need him? This is the section where you introduce yourself as a new person then you should ask your question of the watch repair section. Not everybody checks the entire message board for questions. That means oftentimes questions in the wrong place may go unanswered.

probably nobody can identify the watch because that's not a description for us to tell you what it is it's back to needing a picture and for dedication we need a little more than a picture. But a lot of it depends upon the watch because unfortunately there were a lot of watches made that there just is no identification for

Pics work wonders, they really do.  The most helpful pictures would be: a detailed one of the movement (if you can safely open the back) and a close-up of the pendant-crown-bow (if there is a tiny screw going into the pendant, photograph that side) and pics of any case maker's marks, pics of the dial, pics of the whole thing.  From these we will extrapolate a clearer understanding of your problem.  (I have an idea what it may be already, but I want to be sure.)

A watch of that vintage will unlikely be marked but by using the Bestfit book one my be able to identify it from the keyless work(hand setting and winding mechanism) so pictures ore of the most importance preferably with the dial and hands off the movement, serial numbers and any data from the movement is also helpful

    • OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.
    • Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer. 
    • The stress is the force (on the spring) x distance. The maximum stress is at the bottom, and decreases up the arm. That's why they always break at the bottom. I used a round file, then something like 2000 grit to finish. I gave the rest of the arm a quick polish - no need for a perfect finish. Just make sure there are no 'notches' left from cutting/filing. The notches act like the perforations in your toilet paper 🤣
    • It's probably a cardinal rule for watch repair to never get distracted while at the bench. Yesterday, after finishing a tricky mainspring winding/barrel insertion (I didn't have a winder and arbor that fit very well) I mentally shifted down a gear once that hurdle was passed. There were other things going on in the room as I put the barrel and cover into the barrel closer and pressed to get that satisfying snap. But when I took it out I realized I never placed the arbor.  When opening a barrel, we are relying on the arbor to transfer a concentrically-distributed force right where it is needed at the internal center of the lid. However, when that isn't present it's difficult to apply pressure or get leverage considering the recessed position of the lid, the small holes in the barrel and the presence of the mainspring coils. It was a beat-up practice movement so I didn't take a lot of time to think it over and I pushed it out using a short right-angle dental probe placed in from the bottom, but that did leave a bit of a scratch and crease in the thin lid. I had also thought about pulling it using a course-threaded screw with a minor thread diameter smaller than the lid hole and a major diameter larger, but that may have done some damage as well.  Thinking about how this might have been handled had it been a more valuable movement, is there a method using watchmaking or other tools that should extract the lid with the least damage? 
    • 🤔 what happens if lubrication is placed directly on top of epilame ? Making a small groove so the lubrication doesn't spread across the component but what if when lubing a little overspills and sits on the epilame .
